Hi,
could anyone tell why the program below is able to run the script only
two times:
------
i: 0
result: 10
i: 1
result: 11
i: 2
Segmentation fault: 11 (core dumped)
------
If I remove from JS script access to an external object and change it
to something like "'Hello '+'World'", it runs without issues.
I use revision r3690.
